    摘要: A portable device (200, 210) comprises a power source (70) and a processing system (15, 20, 25, 30, 35) for processing media content received from a service provider (100) via a delivery channel. A control apparatus (50, 60) determines remaining capacity of the power source (70) and receives information from the service provider (100) about available delivery parameters for an item of content. The control apparatus determines an operating duration for the device based on the delivery parameters and the remaining capacity of the power source and sends a request to the service provider (100) specifying at least one delivery parameter for delivery of the content. By specifying what format the service provider (100) should deliver the content, power savings can be made in the processing (20, 30) and rendering (25, 35) stages and in the receive chain of the portable device. Selection of delivery parameters can be automatic or under user control.

    摘要: A gas blower and method according to which the gas is introduced into the inlet of a housing where it is pressurized by rotating impellers. The pressurized gas is directed to a discharge plenum from which a first portion of the gas is discharged. The remaining portion of the gas is passed from the discharge plenum through a plurality of openings to a recirculating chamber for recirculating the gas back to the housing. The gas is passed from the recirculating chamber back to the housing through two radially-spaced sets of angularly-spaced openings formed in the housing.

    摘要: An accelerated vapor recompression apparatus 10 converts incoming flow 35a to a concentrate 35c by developing a concentration profile 146 within a tank 30 holding a liquid 23 containing dissolved solids. The resulting curve 160 of saturation temperature of the stratified liquid 23 (such as a brine 23 or other material 23) moves away from the curve 162 corresponding to fully mixed conditions. The shift 174, 180 in saturation temperature results in increased boiling without increased energy from a heater 70 or compressor 50. A method 90, 200 of control of the system provides interventions 203, 204, 205, 206 at different levels 92, 94, 96, 98 of control, ranging from mass flows 35 to work of a compressor 50, heat from a heater 70, and a predictive processing 215 of feedback 217 for controlling commands 216 algorithmically.
